SAN JOSE -- A federal jury on Wednesday wrapped up its first day of deliberations in the Apple (AAPL) v. Samsung patent trial without reaching a verdict.

The seven-man, two-woman jury is expected to return Thursday morning for another day of deliberations in the multi-billion dollar smartphone and tablet showdown between the two tech giants.

Apple has accused South Korea-based Samsung of copying the designs of the iPhone and iPad in its smartphones and tablets, and has asked the jury to award at least $2.5 billion in damages for patent infringement and other claims.

Samsung has denied copying Apple's products, arguing the Cupertino company is pressing its legal claims to stifle competition in the heated smartphone and tablet market. Samsung also has accused Apple of infringing on some of its patent rights.

With three weeks of evidence to consider, the jury must now fill out a 20-page verdict form that has 33 detailed, multi-layered questions, many of them with elaborate charts that require the panel to consider legal questions for a host of Samsung devices, as well as Apple's. The jury also was given 109 pages of legal instructions, and sent into the jury room with dozens of smartphones and tablets to eyeball.
